For those contemplating a rewatch of Buffy, there are also some good rewatch podcasts to listen to as you go. None of them are perfect but they all bring a slightly different spin on the series.
My favs are:
Boys Watching Buffy ;interesting take from a male perspective)
Buffering The Vampire Slayer (a bit holier than thou at times but some great cast interviews)
The Rewatcher (bit annoying at times as they woefully misinterpret a few things, but good overall)
Juliet Landau (Drusilla) has also launched her own podcast on the series but they’re only on S1 and have already had to reboot it as the format wasn’t working. I’m sticking with it for now as I hope once they get to S2 and Dru appears she’ll have done good behind the scenes insights.
